let’s put the x’s on one side and the numbers on the other (whatever you do to one side, you have to do to the other)
x + 4 = 4x + 2 - 4 - 4x
x - 4x = 2 - 4 -3x = -2 —— —— -3 -3
x = 2/3
to check this, we can put 2/3 in for x (2/3) + 4 = 4(2/3) + 2 4 2/3 = 8/3 + 2 4 2/3 = 2 2/3 + 2 and there we can see both sides equal 4 and 2/3, making it true
